Distributed AP Network Requirements Because Distributed APs are not directly attached to a switch, they require additional support from the network in order to function. • Power - PoE must be provided on one of the Ethernet connections to the AP. Be sure to use a PoE injection device that has been tested by D-Link. Providing PoE on both of the Ethernet connections (on models that have two Ethernet ports) allows redundant PoE. • DHCP - By default, a Distributed AP uses TCP/IP for communication, and relies on DHCP to obtain IP parameters. Therefore, DHCP services must be available on the subnet that the AP is connected to. DHCP must provide the following parameters to the AP: • IP address • Domain name • DNS server address • Default router address • Static IP configuration - If DHCP is not available in the network, a Distributed AP can be configured with static IP information that specifies its IP address, as well as the switch uses as its boot device. • DNS - If the intermediate network between the switch and Distributed AP includes one or more IP routers, create a DLINK.mynetwork.com or wlan-switch.mynetwork.com entry on the DNS server. The entry needs to map one of these names to the system IP address of the switch. The DNS entry allows the AP to communicate with a switch that is not on the AP 's subnet. If the AP is unable to locate a switch on the subnet it is connected to, the AP sends DNS requests to both DLINK and wlan-switch, where the DNS suffix for mynetwork.com is learned through DHCP. • If only DLINK is defined in DNS, the AP contacts the switch whose IP address is returned for DLINK. • If only wlan-switch is defined in DNS, the AP contacts the switch whose IP address is returned for wlan-switch. • If both DLINK and wlan-switch are defined in DNS, the AP contacts the switch whose IP address is returned for DLINK.The AP ignores the IP address returned for wlan-switch. • If both DLINK and wlan-switch are defined in DNS, and the AP is unable to contact the IP address returned for DLINK, the AP never contacts the IP address returned for wlan-switch. The AP does not boot. D-Link DWS-1008 User Manual 104

Distributed AP Network Requirements
Because Distributed APs are not directly attached to a switch, they require additional support from the
network in order to function.
Power
- PoE must be provided on one of the Ethernet connections to the AP. Be sure to
use a PoE injection device that has been tested by D-Link. Providing PoE on both of the
Ethernet connections (on models that have two Ethernet ports) allows redundant PoE.
DHCP
- By default, a Distributed AP uses TCP/IP for communication, and relies on DHCP
to obtain IP parameters. Therefore, DHCP services must be available on the subnet that
the AP is connected to. DHCP must provide the following parameters to the AP:
• IP address
• Domain name
• DNS server address
• Default router address
Static IP configuration
- If DHCP is not available in the network, a Distributed AP can
be configured with static IP information that specifies its IP address, as well as the switch
uses as its boot device.
DNS
- If the intermediate network between the switch and Distributed AP includes one or
more IP routers, create a DLINK.mynetwork.com or wlan-switch.mynetwork.com entry on
the DNS server. The entry needs to map one of these names to the system IP address of
the switch.
The DNS entry allows the AP to communicate with a switch that is not on the AP ’s subnet.
If the AP is unable to locate a switch on the subnet it is connected to, the AP sends DNS
requests to both DLINK and wlan-switch, where the DNS suffix for mynetwork.com is
learned through DHCP.
• If only DLINK is defined in DNS, the AP contacts the switch whose IP address
is returned for DLINK.
• If only wlan-switch is defined in DNS, the AP contacts the switch whose IP
address is returned for wlan-switch.
• If both DLINK and wlan-switch are defined in DNS, the AP contacts the switch
whose IP address is returned for DLINK. The AP ignores the IP address returned
for wlan-switch.
• If both DLINK and wlan-switch are defined in DNS, and the AP is unable to
contact the IP address returned for DLINK, the AP never contacts the IP address
returned for wlan-switch. The AP does not boot.
